-| Backend mixed-source child rows expose stable visible-parent authority | `$env:BROWSER='echo'; $env:PYTHONUTF8='1'; conhost --headless cmd /v:on /c "D:\Repos\hermes-agent\venv\Scripts\python.exe -m pytest tests/test_session_lineage_collapse.py tests/test_session_lineage_metadata_api.py tests/test_5306_subagent_sidebar_flicker.py -v --timeout=60"` | `tests/test_session_lineage_metadata_api.py::test_child_of_hidden_compression_segment_exposes_parent_lineage_root PASSED` | base: base-fails, child metadata exposed `_parent_lineage_root_id` without `_parent_lineage_tip_id`, so the `/api/sessions` serializer had no stable parent-tip field to preserve; head: head-passes, the child row exposes root `lineage_api_root` and tip `lineage_api_tip`, and `_sidebar_session_response_item()` preserves `_parent_lineage_tip_id` on the response payload. |
